*SPARE-TIRE* CARRIER* lAN D RIMA SPREADER.

K VyApplication led September' 28. 15533;.; Serial No. 665,283.

My invention relates to spare tire carriers v for automobiles, and comprises novel. de-

- vices for supporting the` spare tire. My invention also comprises novel means associ-4 ated therewitln'whereby the tire carrier may be; used for the ypurpose of contracting the rim tofacilitate yapplication of the tire and the removal thereof, and also for spreading thev rim into properfposition when the tire hasy been placed. thereon.

Otherffeatures residing in my inventions `fork and prevent late-ral movementy ofthe will vbe later described, andy the novelty vthereof will. be pointed out in the appended claims. f l5 In the drawings:

.Figure 1 is a ViewA in elevation of in-y vention, in position` at the rear of an automobile. Fig. 2 is a vertical transverse section on the line 2-2, Fig. 1.

Fig. 3 is a horizontal section, somewhat enlarged, throughtheworm and its associated elements. v i

Fig. 4 is a view of the wrench or-key which is used in operating the invention.

Figs. 5, 6 and 7 are details of construction which will bedescribed.

In Fig. 1 of the drawings, `the numeral 10 ,indicates a crossbar in anfautomo'bile frame,

ing 12 for the operating elements. The

housing is formed as a back plate 13, pro` vided on its outer face with a circular wall 14, to form a recess in'which is rotatably mounted a worm 15, the latter having on its rear face a gudgeon 16', journaled in a bearing 17, formed in the housing. The worm is provided on its rear face with a helix 18, and on its periphery with a spur or bevel gear 19. A face plate 20 is adapted to cover the recess in the housing 12, and enclose the worm, such face plate having a central lopening 21, which receives a hollow journal 22 on the outer face of the worm, so that thel latter is rotatably supported at both sides.

Radial arms 23, preferably equally spaced about the circumference of the housing, extend from the latter. These radial arms are of tubular formation, and constitute guides for adjustable rods composed of telescoping sections 24 and 25, one being threaded into the other. The threaded connection between the two sections :may be placed at any points in their respective llengths as will enable them to meer. the requirements in adm vto which a bracket or ybrackets 11 maybei attached. The brackets 11 support ahous-l.

justingthe device for tires of different sizes.

@The outerends ofthe severa-l'sections 24: are

in the rotationof the worm, the adjustable rods will be retracted or` advanced in a simultaneous movement. i

Each section 25 isprovided at its free end with a -shoe\26, extending transversely of the vrim .27 carrying: the tire, thenshoe having projections at-Leach end to form a rim from the position in which it is placed. The rear projection 28 is somewhat,` elongated, and formed at its pend with an-fin wardly extending1hook/29pone :for each of the radial and adjustable rods, which hooks are adapted to engage thefrimi in the mannerfshown in Fig. 6,'to contract the rim when theworm is rotated` inl direction to achieve that result.. ,j

For the purposel of.k preventing the-hooks 129 fromchafing ithewtirefsupported on the carrier, I providehinged metal= shields 30,

1 which are Iadapted' tofbe folded into the y-dottednline position? indicated in Fig. 6, and y tofbe turned back to full line-position when theirim isto be contracted.` j l i j Thegspur gear 15 maybe rotated at differentspeeds, dependent rupon the resist-` ance encountered. y ,Fig 4. shows'a T-wrench ,.32 which Luse-atsuchftimes, Airone end, the kwrench is Vformed with apinion 33,- for engaging the gear 19 of the worm, giving a slow movement of rotation to theV latter, the end in advance of the pinion being seated in a recess 34, formed in the housing 12. Thisarrangement will permitthe application of great power when necessary by reason of the reduction in the gear ratio, as shown. But a quicker and direct movement of rotation may bek given to the worm by inserting the polygonal head 35 of the wrench in the correspondingly formed socket 36, in the journal 22 at the face of the worm.

Expansion of the rim into position within the tire 37, is effected by the outward movement of the radially arranged adjustllo 23, to accommodate radial rods 2l, 25 oi' greater length for use in connection With tires of larger sizes, the mechanism shown may be extended by means of sleeves 39, joined thereto, as in Fig. 7.V Such sleeves will be packed at their outer ends, as before.

A second spare tire may be supported by means of brackets/i0, see Fig. 5, attached to the shoes 26, as shown in Fig. 2. A clevis 4l may be attached to the pivot, of one of the shields 30, and a chain 4l", encircling the tire, be employed to guard the latter against unauthorized removal, a padlock connecting the free end of the chain to an eye 42, Vfixed upon the shoe.

For the purpose of preventing operation of the worm fraudulently, I hinge a plate 43 to the housing 12, as at 44, such plate being in the form of a hasp and adapted to cover the openings in the face plate 2O ot the housing, so as to 'prevent the application of the Wrench. A padlock engaging a staple fixed in the cover plate 20, holds the hasp in eiiective position.

A hexagonal projection 4-5 is formed upon theinner face of the plate a3, such projection being adapted to enter the recess 3G in the journal 22, so that the parts of the tire carrier, will be eifectively locked against accidental movement.

' Having thus described my invention, what I claim and desire to secure by Let ters Patent of the United States, is;-V

" l. Al spare tire carrier adapted to be 'mounted on the cross bar of an automobile frame, comprising a housing 1n which 1sV journalled a gear having a Worm on one `-face, radially movable connecting rods engaging the said Worm gear at one end, and

axis with a Wrench receiving socket for roY tating at a different speed.

2. A spare tire carrier adapted to be mounted on the cross bar of an automobile frame, comprising a lhousing in which is journalled a gear having a Worin on one. face, radially movable connecting rods engaging the said Worm gear at one end, and the tire rim at the other, means for rotating the said gear, hooks at the ends of' the said connecting rods to engage the rim to contract theV same, and means covering the said hooks to prevent chaiing the tire when supported on the rim.`

3.1K spare tire carrier adapted to, be mounted on the cross bar of an automobile frame, comprising a housing in Which is journalled a gear having a Worm on one face, radially movable connecting rods engaging the said Worm gear at one end, and the tire rim at the other, means for rotating the saidV gear, hooks at the ends oli the said connecting rods to engage the rim toI gaging the said Worm gear at one end, andthef tire rim at the other, tubular guides for the said connecting rods, and means for extending the said guides to accommodate lengthened connecting rods.

In testimony whereof, I have signed my name at Milwaukee, this 22nd day of September, 1923.
